Concept explainers

Wien's displacement law

Students often get confused between Wien's displacement law and Planck's radiation law. Although both are historically related, yet they are conceptually different. Planck's law helps determine the spectrum of a blackbody, while Wien's law determines the relationship between peak wavelength and temperature.

Earth’s surface absorbs an average of about 960. W/m2 from the Sun’s irradiance. The power absorbed is Pabs = (960. W/m2) (Adisc), where Adisc = π(RE)2 is Earth’s projected area. An equal amount of power is radiated so that Earth remains in thermal equilibrium with its environment at nearly 0 K. Estimate Earth’s surface temperature by setting the radiated power from Stefan’s law equal to the absorbed power and solving for the temperature in Kelvin. In Stefan’s law, assume e = 1 and take the area to be A = 4π(RE)2, the surface area of a spherical Earth. (Note : Earth’s atmosphere acts like a blanket and warms the planet to a global average about 30 K above the value calculated here.)
